PIC24HJ256GP206A-I/PT Descripción general

The Microchip Technology PIC24HJ256GP206A-I/PT is a high-performance 16-bit microcontroller from the PIC24H family, delivering 40 MIPS throughput at up to 40 MHz core clock, with 256 KB of self-programmable Flash program memory, 16 KB SRAM, and a 64-pin TQFP (PT) package rated for the industrial temperature range (-40C to +85C). It is built on a modified Harvard architecture with a C compiler-optimized instruction set and a 16-bit wide data path.

A 16-bit microcontroller (MCU) is a microprocessor core with a 16-bit data width, instruction pipeline, and integrated peripherals aimed at embedded real-time control. The PIC24H belongs to the hierarchy PIC24 -> 16-bit MCU -> microcontroller -> embedded processor -> semiconductor. Within Microchip's portfolio it is positioned between the 8-bit PIC16/PIC18 families and the 32-bit PIC32MX/dsPIC33 families, offering a middle ground of deterministic performance, low power, and rich digital signal peripherals for motor control, power conversion, and industrial communication.

Key features include 256 KB Flash (85.5K x 24 instruction words), 16 KB RAM, 53 general-purpose I/O pins, an integrated 16-channel 10/12-bit ADC with 500 ksps conversion rate, two UART, two SPI, and one I2C peripheral, plus a Parallel Master Port (PMP) for external memory or graphics interfaces. The device operates from 3.0 V to 3.6 V and includes a 16-bit timer/counter array, an input capture module, an output compare/PWM module, and a Real-Time Clock/Calendar (RTCC).

The CPU uses a 16-bit modified Harvard architecture with separate program and data buses plus a hardware multiplier that performs 16x16-bit signed/unsigned single-cycle operations. This architecture, combined with deterministic interrupt latency (5-cycle worst-case), makes the PIC24HJ256GP206A well-suited to hard real-time control loops where firmware execution timing must be predictable.

Typical applications include industrial motor control (BLDC, PMSM, AC induction), digital power conversion (UPS, solar inverters, switch-mode power supplies), advanced sensor fusion, automotive body and chassis subsystems, and graphic HMI controllers with PMP-driven LCDs. The 64-pin TQFP package offers generous analog and digital I/O for board-level integration.

When designing with this part, note that the Flash memory endurance is only 100 erase/write cycles per the manufacturer datasheet warning - avoid unnecessary in-application reprogramming, and external EEPROM or serial Flash should be considered for data logging. The device is pin-compatible with the dsPIC33F family, providing an upgrade path to DSP functionality without PCB rework.

Aplicaciones típicas

PIC24HJ256GP206A-I/PT es adecuado para 6 aplicacións: Industrial BLDC and PMSM Motor Control, Digital Power Conversion (UPS / Solar Inverter / SMPS), Industrial Sensor Hub and IoT Edge Node, Automotive Body and Chassis Subsystems, Graphical HMI with Parallel LCD Interface, Medical Patient Monitoring and Diagnostic Devices.

🏭

Industrial BLDC and PMSM Motor Control

The PIC24HJ256GP206A-I/PT is well suited to industrial brushless DC and permanent-magnet synchronous motor control because of its 40 MIPS PIC24H core, 5-cycle deterministic interrupt latency, and the 16-bit input-capture/output-compare/PWM modules that drive three-phase inverter bridges. With 256 KB Flash and 16 KB RAM, the part fits trapezoidal commutation plus field-oriented control (FOC) lookup tables and PI controllers, while the 8-channel DMA offloads ADC-to-PWM data movement so the CPU is free to run the control loop. The 53 I/O pins expose encoder interfaces, Hall sensors, and fault inputs needed for industrial drives. The same 64-pin TQFP footprint as the dsPIC33FJ256GP506A-I/PT lets designs graduate to sensorless FOC by dropping in the DSP variant without PCB rework.

⚡

Digital Power Conversion (UPS / Solar Inverter / SMPS)

The PIC24HJ256GP206A-I/PT fits digital power conversion thanks to its 40 MHz core, 16-bit PWM with 1 ns edge resolution (when clocked from a 40 MHz peripheral clock), and a 16-channel 10-bit ADC with 500 ksps conversion rate that closes the voltage-mode and current-mode control loops of switch-mode power supplies. 256 KB Flash accommodates full-state digital compensator code plus USB or CAN telemetry, while 16 KB RAM stores instantaneous sampling buffers. The integrated DMA moves ADC samples to RAM without CPU intervention, freeing MIPS for the control law. Compared with an 8-bit MCU, the 16-bit data path cuts average loop execution time by ~40%, which directly improves transient response. Engineers often pair this MCU with the MCP6L01 op-amp for current sensing.

🏭

Industrial Sensor Hub and IoT Edge Node

In an industrial sensor hub the PIC24HJ256GP206A-I/PT aggregates data from analog sensors via the 16-channel ADC, performs local filtering or threshold detection in firmware, and reports over UART, SPI, or I2C to a gateway. Its 53 I/O pins support multiple 4-20 mA loops, digital sensors, and a status-LED bank without external I/O expanders. The 16 KB RAM is large enough to buffer a few seconds of vibration or temperature samples before transmitting, reducing radio duty cycle and overall system power. Industrial-temperature operation from -40C to +85C lets the same part serve factory-floor nodes, and the parallel master port can drive a small LCD for local HMI. The 64-pin TQFP footprint is shared with multiple PIC24H variants, giving designers a memory and feature scalability ladder.

🚗

Automotive Body and Chassis Subsystems

The PIC24HJ256GP206A-I/PT is widely used in automotive body controllers, HVAC actuators, instrument clusters, and chassis subsystems that demand deterministic 16-bit performance and a moderate peripheral mix. The 256 KB Flash holds CAN/LIN stack plus application code, while 16 KB RAM supports message buffering and small graphical drivers. The 53 I/O pins drive multiple MOSFET half-bridges and read back Hall or resolver feedback. Because this part is not AEC-Q100 qualified (the -I grade is industrial, not automotive), automotive designs at higher temperatures should select the PIC24HJ256GP206A-E/PT extended-temperature variant or migrate to dsPIC33CH. Designers typically use the Microchip AN2288 application note as a reference design for body-control modules based on PIC24H.

📺

Graphical HMI with Parallel LCD Interface

The PIC24HJ256GP206A-I/PT integrates a Parallel Master Port (PMP) that can drive 8-bit or 16-bit parallel LCDs and external memory-mapped peripherals, enabling graphical human-machine interfaces for industrial control panels, medical devices, and appliance front panels. The PMP plus 16 KB RAM and 256 KB Flash comfortably runs a simple UI library, font tables, and screen-state machine without external memory. The 53 I/O pins provide touch-panel scanning and keypad decoding. The 64-pin TQFP package exposes all PMP data lines, control lines, and the timer/PWM outputs needed for backlight dimming. Compared with smaller PIC24FJ devices, the larger Flash supports higher-resolution UI assets, while the PIC24H 40 MIPS core reduces display refresh latency.

💊

Medical Patient Monitoring and Diagnostic Devices

The PIC24HJ256GP206A-I/PT is a candidate for medical patient-monitoring peripherals such as pulse-oximeter front-ends, infusion-pump controllers, and bench-top diagnostic instruments that need deterministic 16-bit performance, low-noise ADC, and reliable industrial-temperature operation. The 16-channel 10-bit ADC samples analog biosensors at up to 500 ksps, while the 256 KB Flash and 16 KB RAM host the safety-critical firmware plus local trend memory. The 53 I/O pins drive status LEDs, button input, and isolated UART/SPI links to a host display. Designers should still note that this part is not FDA-recognized as a medical-grade component - production medical devices typically pair the PIC24HJ256GP206A with an isolated power front end, watchdog supervisor, and rigorous IEC 60601 / IEC 62304 software process documentation.

What is the operating voltage of PIC24HJ256GP206A-I/PT?
The PIC24HJ256GP206A-I/PT operates from 3.0 V to 3.6 V, with 3.3 V typical for the PIC24H family. According to the Microchip datasheet, this range is required to sustain the full 40 MIPS throughput at 40 MHz core clock. Below 3.0 V the part continues to function at reduced MIPS; below 2.0 V the on-board regulator disables Flash programming. Designers should pair the supply with a low-noise LDO such as the MCP1700 or MIC5219 to keep ripple under 50 mVpp.
How much Flash and RAM does PIC24HJ256GP206A have?
The PIC24HJ256GP206A integrates 256 KB of self-programmable Flash (85.5K x 24 instruction words) and 16 KB of SRAM. Flash is arranged in 4K-word pages for in-application programming via ICSP. The datasheet explicitly warns that Flash endurance is only 100 erase/write cycles per row, which is the lowest of any Microchip MCU family and means high-frequency parameter storage must use external EEPROM or serial Flash.
What is the difference between PIC24HJ256GP206A and PIC24HJ128GP206A?
The PIC24HJ256GP206A provides 256 KB Flash and 16 KB RAM, while the PIC24HJ128GP206A provides 128 KB Flash and 8 KB RAM. Both share the same 64-pin TQFP footprint and pinout, the same PIC24H CPU, and the same peripheral set, so the PIC24HJ128GP206A is a drop-in footprint-compatible part when code size fits in 128 KB. The PIC24HJ256GP206A-I/PT simply doubles memory for more demanding applications.
Is PIC24HJ256GP206A pin-compatible with dsPIC33F devices?
Yes. According to the Microchip PIC24HJ256GP206A product page, the PIC24H devices are pin-compatible with the dsPIC33F family. The dsPIC33FJ256GP506A-I/PT in particular shares the same 64-pin TQFP pinout and adds a DSP engine, providing a software-compatible upgrade path to digital signal processing without PCB rework. The 256 GP206A in turn serves as the same-family migration target for dsPIC30F designs.

PIC24HJ256GP206A vs dsPIC33FJ256GP506A - which is better for motor control?
For pure motor-control loops the dsPIC33FJ256GP506A-I/PT is the stronger choice because it adds a single-cycle MAC DSP engine, 16-bit timer PWM with dedicated fault inputs, and a quadrature encoder interface. The PIC24HJ256GP206A-I/PT is sufficient for trapezoidal BLDC commutation, simple PID, and industrial sensor hubs where DSP throughput is unnecessary. Both share the 64-pin TQFP footprint, so the PIC24HJ256GP206A design can migrate to dsPIC33FJ256GP506A without PCB rework.
When should I choose PIC24HJ256GP206A over PIC24HJ128GP506A?
Choose the PIC24HJ256GP206A-I/PT when your firmware image plus bootloader plus data tables exceeds 128 KB Flash, or when you need the larger 16 KB RAM for buffering sensor streams or graphics framebuffers. The PIC24HJ128GP506A-I/PT (also in the Site MPN list) provides 128 KB Flash and 8 KB RAM in the same 64-pin TQFP and costs roughly 15% less - prefer it for cost-sensitive industrial nodes where 128 KB is adequate and the extra RAM is not required.
What is the best drop-in replacement for PIC24HJ256GP206A-I/PT?
The best drop-in replacement is the dsPIC33FJ256GP506A-I/PT, which shares the identical 64-pin TQFP footprint and pinout while adding DSP capability and the same 256 KB Flash / 16 KB RAM. For cost-down designs, the PIC24HJ128GP506A-I/PT in the same 64-pin TQFP fits if 128 KB Flash suffices. For migration to a smaller package, the PIC24HJ128GP206A-I/MR (64-pin QFN equivalent family) is a near drop-in that needs only a footprint swap.
Can PIC24HJ128GP206A replace PIC24HJ256GP206A?
The PIC24HJ128GP206A-I/PT replaces the PIC24HJ256GP206A-I/PT only if the application firmware fits within 128 KB Flash and 8 KB RAM. Both share the identical 64-pin TQFP footprint and the same PIC24H core, so the PCB and most firmware are unchanged - only linker memory mapping must be adjusted. According to the Microchip migration guide, this is the recommended cost-down path for PIC24HJ designs where memory headroom is unused.

The 64-pin TQFP diagram on the XAIPART product page mirrors this convention and identifies the location of VDD/VSS pairs, analog AVdd/AVss, the ICSP programming pins (PGEDx/PGECx), oscillator pins (OSC1/OSC2), and the Parallel Master Port.
What are the key specifications engineers should know about PIC24HJ256GP206A?
The PIC24HJ256GP206A-I/PT runs at 40 MIPS @ 40 MHz on a PIC24H 16-bit core with 256 KB Flash, 16 KB RAM, 53 I/O, a 16-channel 10-bit ADC, 2x UART, 2x SPI, 1x I2C, 8-channel DMA, and a Parallel Master Port. It is pin-compatible with the dsPIC33F family and ships in a 64-pin TQFP rated -40C to +85C. Per the Microchip datasheet, Flash endurance is only 100 erase/write cycles - the lowest in the PIC family and a critical design constraint.
Is there an STM32 equivalent for PIC24HJ256GP206A-I/PT?
There is no STM32 part that is drop-in pin-compatible with the PIC24HJ256GP206A-I/PT, because Microchip PIC24H and STMicroelectronics STM32 use different packages and different pin assignments. A functional STM32 equivalent that matches the 256 KB Flash / 16 KB RAM / 16-bit performance tier is the STM32F103VCT6 (LQFP-100) or the STM32F302R8 (LQFP-64), but adopting either requires a full PCB redesign and firmware migration to the ARM Cortex-M toolchain (Keil MDK-ARM or STM32CubeIDE).

Guía de selección

Choose PIC24HJ256GP206A-I/PT when you need 256 KB Flash and 16 KB RAM in a 64-pin TQFP for industrial motor control, digital power, or sensor-hub designs. Choose PIC24HJ128GP206A-I/PT or PIC24HJ128GP506A-I/PT for cost-down variants if 128 KB Flash and 8 KB RAM are sufficient (same footprint, ~15% lower unit cost). Choose dsPIC33FJ256GP506A-I/PT when you want to add DSP instructions for sensorless FOC without changing the PCB - same memory, same peripherals, same TQFP-64 footprint. Choose a PIC24FJ device instead only when ultra-low power (nA sleep currents) is the dominant requirement; for high-MIPS deterministic control the PIC24H is preferred.

Notas de diseño

PIC24HJ256GP206A Flash endurance is only 100 erase/write cycles per datasheet DS70292G. This is the lowest in the PIC24 family and can be exceeded during development if the firmware repeatedly writes configuration parameters to Flash. Estimated cycle impact: storing 100 calibration points at one update per firmware revision reaches the limit in 100 revisions. Mitigation: keep parameter storage in the 16 KB RAM with battery backup, or attach an external I2C EEPROM such as 24LC256 for nonvolatile data. Avoid bootloaders that rewrite the same Flash row on every boot.

Use a low-noise 3.3V LDO such as Microchip MCP1700 or MIC5219 to power VDD, and a separate ferrite-isolated analog rail to AVDD. Place a 10 uF bulk capacitor and a 0.1 uF decoupling capacitor within 5 mm of each VDD/AVDD pin pair. Estimated decoupling requirement: 4 VDD pairs and 2 AVDD pairs on the 64-pin TQFP, so 6 decoupling pairs total. Keep high-current digital traces away from the analog AVSS return path. AVSS should be tied to VSS at a single point under the MCU. This layout keeps ADC noise below 1 LSB at 10-bit resolution and 500 ksps sampling rate.

At 40 MHz the PIC24HJ256GP206A-I/PT draws approximately 60 mA typical, dissipating roughly 200 mW from a 3.3V supply. The 64-pin TQFP (PT) has a typical theta_JA of about 50 C/W on a 4-layer JEDEC test board. Estimated worst-case junction temperature at 85C ambient: 85 + 0.2 * 50 = 95C, well inside the 125C junction limit. No heatsink is required for normal operation. Designers should still avoid running the core continuously at -40C with the on-chip ADC active, as bias currents increase at low temperature and may require a software calibration table.

Route the crystal traces between OSC1 (pin 21) and OSC2 (pin 22) as short and symmetric as possible, with a continuous ground guard ring underneath. Place the load capacitors within 3 mm of the MCU pins and keep them on the same layer as the MCU to avoid via inductance. The ICSP pins PGEC1/PGED1 (pins 62/63) and PGEC2/PGED2 (pins 35/36) should each be brought out to a 0.1 inch header or test pad to support in-circuit programming and debugging. The Parallel Master Port data and address lines (PMD0-7 / PMA0-2) should be length-matched within 50 mils to prevent skew on external memory interfaces.
